ELECTRICAL WORK
Only perform installation in dry conditions.
Fig.38
Abide with the safety regulations for all other components used in the system, including wiring
and cables, connectors, charging regulators, inverters, storage batteries and rechargeable
batteries, etc.
Use only equipment, connectors, wiring and support frames suitable for use in solar electric
systems. Always use the same type of module within a particular photovoltaic system.
The module frame must be properly grounded. The grounding wire must be properly fastened to
the module frame to assure good electrical contact. Use the recommended type, or an equivalent,
connector for this wire.

Under normal outdoor conditions the module will produce current and voltages that are different
than those listed in the data sheet. Data sheet values are values expected at standard test
conditions. Accordingly, during system design, values of short-circuit current (Isc) and open-
circuit voltage (Voc) marked on UL series modules should be multiplied by a factor of 1.25
when determining component voltage ratings, conductor amperage, fuse size and size of controls
connected to the module or system output.
The hole in the back of the module frame is used to drain the water, do not block it.
Mechanical installation
Select a suitable place for installation of the module. The module should not be shaded at any
time of the day.
The module should be facing due south in northern latitudes and due north in southern
latitudes for best power production.
For detailed information on the best elevation tilt angle for the installation, please consult
with the solar photovoltaic system supplier.
Do not use module near the place where flammable gas may be generated or collected.
